+Using nshmp-haz with Matlab
+---------------------------
+
+All recent versions of Matlab include a Java runtime environment and it is therefore relatively straightforward to access the nshmp-haz library.
+
+#### Requirements
+
+* Matlab R2013B or higher (nshmp-haz targets Java 7; prior versions of Matlab use Java 6).
+* A [build](/usgs/nshmp-haz/wiki/Building-&-Running) of nshmp-haz.
+*
